# Babelcast

A server which allows audio publishers to broadcast to subscribers on a channel, using nothing more than a modern web browser.

It uses websockets for signalling & WebRTC for audio.

The designed use case is for live events where language translation is happening.

A translator would act as a publisher and people wanting to hear the translation would be subscribers.

## Building

Download a [precompiled binary](https://github.com/porjo/babelcast/releases/latest) or build it yourself.

## Usage

```

Usage of ./babelcast:

  -debug

        enable debug log

  -port int

        listen on this port (default 8080)

```

Then point your web browser to `http://localhost:8080/`

If the `PUBLISHER_PASSWORD` environment variable is set, then publishers will be required to enter the

password before they can connect.

### TLS

Except when testing against localhost, web browsers require that TLS (`https://`) be in use any time media devices (e.g. microphone) are in use. You should put Babelcast behind a reverse proxy that can provide SSL certificates e.g. [Caddy](https://github.com/caddyserver/caddy).
